Reaching heights of 4 to 6 feet, this clump-forming plant adds dramatic vertical interest to borders, meadows, and rain gardens. Its tolerance for wet soils and ability to attract pollinators make it a valuable addition to native plant landscapes.\u003c\/p\u003e\u003cp\u003eThis heirloom, non-GMO variety is grown for its reliable performance and ecological benefits.

Press seeds lightly into the soil surface; they need light to germinate. Keep the growing medium consistently moist but not waterlogged. Germination typically occurs in 10-21 days at temperatures around 65-70°F (18-21°C). Once seedlings have several true leaves, transplant them outdoors after hardening off, spacing them 18-24 inches apart in a sunny location.\u003c\/p\u003e\u003cp\u003eSwamp Sunflower is relatively low-maintenance once established. Water regularly during dry spells, especially in the first growing season. Tall stems may benefit from staking in windy areas. Divide clumps every few years to maintain vigor. Deadhead spent flowers to encourage additional blooms or leave seed heads for birds.\u003c\/p\u003e\u003ch2\u003eWhat's Included\u003c\/h2\u003e\u003cp\u003e100 Swamp Sunflower seeds.\u003c\/p\u003e","brand":"Blake's Flora \u0026 Soil","offers":[{"title":"Default Title","offer_id":67862012199222,"sku":"FSG-235","price":11.67,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0994\/4884\/8694\/files\/il_fullxfull.7788021816_rtrg.jpg?v=1793267883","url":"https:\/\/blakesflora.com\/products\/100-swamp-sunflower-seeds-heirloom-non-gmo-wildflower-for-native-garden-planting","provider":"Blake's Flora \u0026 Soil","version":"1.0","type":"link"}
